<![CDATA[The Civil Servant Investigator is one of the law enforcement officers that has the function to carry out an investigation process that is given special authority to carry out an investigation process for a violation of the Regional Government Legal Product (PERDA) which contains elements of criminal acts. Usually the crime is not a general crime that can be handled by police investigators. In making the decision on the selection of Civil Servant Investigators (PPNS) at the Medan Sumatera River Region II Medan the writer uses the Electre method, where Electre is one of the methods for determining the order or priority in MCDM (Multi-Criterion Decision Making). In the use of decision support systems with the Electre method will provide a matching rating value for each alternative. In it all data are combined into one with the weight of the assessment that has been obtained through test assessment. The author tries to design and build a decision support system for the selection of Civil Servant Investigators using the Electre method, providing information needed by the committee in making decisions and applying the Electre Method in determining the Civil Servant Investigator Balai Sumatera River Region II Medan Medan Decision support system is not a making tool decision, but rather a system that helps decision makers by equipping them with information from data that has been processed with relevance and is needed to make decisions about an issue more quickly and accurately]]>

<![CDATA[Compression is a reduction in the size of the data to a smaller size than the original. The technique of compression is to replace the repetitive character with a certain pattern so that the data can minimize its size. Therefore the data that will be stored needs to be compressed first so that the size becomes smaller. The advantage of pdf files is that the pdf file format can not only store data in text form but also can save an image (image) or photo. In storing in pdf files, the data that will be stored is not susceptible to viruses. One pdf file compression technique that can compress images well is compressing pdf files using the J-Bit Encoding method. J-Bit Encoding (JBE) is an algorithm that optimizes input for other compression algorithms, thus the compression algorithm will be better if it is combined with the J-Bit Encoding method.]]>

<![CDATA[Digital imagery is currently very widely used, so it is very vulnerable to data theft by unauthorized parties. In order to maintain the security of digital images can be done by using cryptographic techniques. Cryptographic techniques can encode digital images by encrypting them in the form of passwords that are not understood. ICE is a block cipher published by Kwan in 1997. This algorithm has a structure similar to DES, but with additional bit permutations that do not depend on the key in the rotation function. There are various types of ICE variants, namely Thin-ICE, ICE standard, and ICE-n. The difference between the three is the length of the keyword used and the number of rounds. The Thin-ICE algorithm uses 64 bits and 8 turns. The ICE standard uses 64 bits and 16 round keys. The ICE-n algorithm uses keys 64n bits and 16n turns. The use of this type of algorithm can be adjusted to the needs of users where Thin-ICE has the lowest level of security among the three, while ICE-n is the highest. This algorithm does not become the subject of a patent and the source code can be used freely.Keywords : Cryptography, Digital Image,Algorithm,ICE.]]>

<![CDATA[PT. Boenk Cosmetic Manufacture is a factory that developed in 2013 in order to deal with globalization, in addition to the large market interest in the products of this factory so as to maintain the factory's existence and consistency, this plant was developed. This company has fulfilled CPKB (How to Make Cosmetics better). PT.Boenk Cosmetic Manufacture every month experiences the addition of new members based on the passage of time members will increase. The problems that are often faced by the employees of PT. Bunk Cosmetic Manufacture increasingly unstructured member data management when searching for member data information that resulted in repeated errors. And every month it is difficult to get fast and precise member data search results so that the work process takes a lot of time. To overcome these problems, it is necessary to develop a system by implementing string matching algorithms to minimize errors in desktop-based member data search. Used in this research is the Boyer Moore algorithm. Boyer Moore's algorithm was first published by Robert S. Boyer, and J. Strother Moore in 1977. By starting character matching from a fixed window shift from left to right. If a match occurs then a comparison of the character of the text and the character of the previous pattern, ie equally reducing the index and pattern of each by one. By using this algorithm the search process will be faster and a lot of information obtained.]]>

<![CDATA[Decision Support System is a system that can help management in making the right decision, which is needed at a management level. Likewise at the Lubuk Pakam Sub-District Office in selecting the best village head. So far, the Camat Office has never determined the best village head in Lubuk Pakam Subdistrict, so that it encounters obstacles in choosing the village head election. SPK is able to provide alternative solutions to semi / unstructured problems for individuals or groups and in a variety of decision making processes and styles, SPK uses data, databases and analyzes of decision models. Seeing this, researchers are interested in conducting research by applying the Extended Promethee II (EXPROM II) method to elect the best village head in a decision support system. It is expected that the results of the research can help the Lubuk Pakam sub-district]]>

<![CDATA[The rapid development of information technology requires users to be more careful in maintaining data confidentiality and security so that data is not known or manipulated by other parties. Data security is very important for users, data security can be maintained by everyone. Cryptography is one of the security tools used to encode a document file. One of them is by using the Massey-Omura algorithm, which is an asymmetric cryptographic algorithm, so that it has different keys for encryption and decryption. In the process of sending data, it also requires the duration of sending files to not give an opportunity to data thieves by compressing the data or reducing the size of the file to be smaller without losing the contents of the document file, so the data exchange process can be shorter Data compression is a process where text, audio, and video files are transformed into compressed files with smaller data sizes but do not lose the actual information. This study discusses the type of lossless compression, so that files obtained from decompression will be identical to the original data. Elias Delta Code is a type of lossless compression. The performance parameters of this algorithm will be measured by Ratio of Compression (RC, Space Saving (SS) and compression time. Data used in the testing process is data that consists of several types of characters. In this discussion will include explanation, how to work, advantages and The author will also try to provide a review of ways to improve the security level of document files.]]>

<![CDATA[The development of information technology now allows storing data in a very large time. This development has added to various fields, including credit facilities, so that the use of information technology in public institutions. Data mining is an activity that includes gathering the use of historical data to find the regularity of patterns, or relationships in large data. The process of predicting the number of customer loans so far in the savings and loan cooperatives is still based on looking directly at the loan amount of the customers and seeing the general ledger records in the cooperative. The application of the C4.5 algorithm is a case-solving solution that is often used in problem solving on classification techniques that have characteristics namely by the process of determining the entropy value and gain value from the possibility that each criterion is a reference decision followed by the process of the decision tree]]>
